Low-Frequency Gravitational Bremsstrahlung and Memory in a Medium
Diego Blas, Silvia Gasparotto, Hitoshi Murayama +2
Gravitational radiation from the early Universe offers a powerful window into physics beyond the Standard Model (SM). In this paper, we investigate the low-frequency tail of gravit…
Observing Leptogenesis in Action with Gravitational Waves
Hitoshi Murayama, Bea Noether, Jan Schütte-Engel
Leptogenesis is arguably the best motivated theory of baryogenesis given the discovery of finite neutrino masses, yet its experimental test is elusive given its high energy scale.…
Double-graviton production from Standard Model plasma
J. Ghiglieri, M. Laine, J. Schütte-Engel +1
The thermal plasma filling the early universe generated a stochastic gravitational wave background that peaks in the microwave frequency range today. If the graviton production rat…
Searching for High Frequency Gravitational Waves with Phonons
Yonatan Kahn, Jan Schütte-Engel, Tanner Trickle
The gravitational wave (GW) spectrum at frequencies above a kHz is a largely unexplored frontier. We show that detectors with sensitivity to single-phonon excitations in crystal ta…
The statistics and sensitivity of axion wind detection with the homogeneous precession domain of superfluid helium-3
Joshua W. Foster, Christina Gao, William Halperin +5
The homogeneous precession domain (HPD) of superfluid He has recently been identified as a detection medium which might provide sensitivity to the axion-nucleon coupling $g_{…
MAGO2.0: Electromagnetic Cavities as Mechanical Bars for Gravitational Waves
Asher Berlin, Diego Blas, Raffaele Tito D'Agnolo +5
Superconducting cavities can operate analogously to Weber bar detectors of gravitational waves, converting mechanical to electromagnetic energy. The significantly reduced electroma…
Freezing-In Gravitational Waves
Jacopo Ghiglieri, Jan Schütte-Engel, Enrico Speranza
The thermal plasma in the early universe produced a stochastic gravitational wave (GW) background, which peaks today in the microwave regime and was dubbed the cosmic gravitational…
Axion wind detection with the homogeneous precession domain of superfluid helium-3
Christina Gao, W. P. Halperin, Yonatan Kahn +3
Axions and axion-like particles may couple to nuclear spins like a weak oscillating effective magnetic field, the "axion wind." Existing proposals for detecting the axion wind sour…
Axion detection with phonon-polaritons revisited
David J. E. Marsh, Jamie I. McDonald, Alexander J. Millar +1
In the presence of a background magnetic field, axion dark matter induces an electric field and can thus excite phonon-polaritons in suitable materials. We revisit the calculation…
Detecting High-Frequency Gravitational Waves with Microwave Cavities
Asher Berlin, Diego Blas, Raffaele Tito D'Agnolo +4
We give a detailed treatment of electromagnetic signals generated by gravitational waves (GWs) in resonant cavity experiments. Our investigation corrects and builds upon previous s…
Axion Quasiparticles for Axion Dark Matter Detection
Jan Schütte-Engel, David J. E. Marsh, Alexander J. Millar +7
It has been suggested that certain antiferromagnetic topological insulators contain axion quasiparticles (AQs), and that such materials could be used to detect axion dark matter (D…
Gravitational Waves as a Big Bang Thermometer
Andreas Ringwald, Jan Schütte-Engel, Carlos Tamarit
There is a guaranteed background of stochastic gravitational waves produced in the thermal plasma in the early universe. Its energy density per logarithmic frequency interval scale…
SCYNet: Testing supersymmetric models at the LHC with neural networks
Philip Bechtle, Sebastian Belkner, Daniel Dercks +6
SCYNet (SUSY Calculating Yield Net) is a tool for testing supersymmetric models against LHC data. It uses neural network regression for a fast evaluation of the profile likelihood…
